The Atlas Copco 1621700408 (=1621600908) after cooler core stands as a critical component for the ZR 300 to ZR 425 series of oil-free rotary screw air compressors. This genuine cooler core effectively dissipates heat from compressed air, designed to lower discharge air temperatures, drop out moisture efficiently, and preserve peak volumetric performance.

Product Overview

The Atlas Copco ZR series compressors utilize water to cool the compressed air, and the after cooler core forms the heart of this cooling system. By removing heat immediately after the final compression stage, this component prevents thermal stress on valves, dryers, and other sensitive equipment downstream.

For operators of Atlas Copco ZR300, ZR315, ZR355, ZR400, and ZR425 oil-free compressors, the after cooler core plays an indispensable role in maintaining system reliability. Without effective after-cooling, compressed air retains excessive heat that can damage downstream equipment, reduce production efficiency, and compromise air quality. This cooler core directly addresses these challenges through superior heat exchange technology.

We supply this high-quality after cooler core, sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. as brand-new genuine original merchandise. We maintain a strict supply chain that guarantees every unit we deliver meets the exacting standards of the original manufacturer.

Key Features and Advantages

Superior Heat Exchange Efficiency

The after cooler core effectively reduces the temperature of compressed air, enhancing overall system efficiency and protecting downstream components. This efficient heat transfer translates directly into lower operating temperatures, reduced thermal stress on equipment, and more consistent air quality for your production processes.

Robust Construction for Demanding Environments

Atlas Copco crafts this cooler core from high-quality materials designed to withstand the most demanding industrial environments. The durable construction ensures longevity and reliable performance even under continuous heavy-duty operation. When you choose this genuine part, you invest in years of dependable service.

Precision Compatibility

This cooler core is specifically engineered for the ZR300 to ZR425 models. This precision design ensures seamless integration and optimal performance without the fitment issues that often plague substitute parts. Every dimension, every connection point, and every thermal characteristic matches the original specifications perfectly.

Moisture Removal Enhancement

By reducing the temperature of compressed air, the after cooler core promotes effective moisture condensation and removal. This feature protects your air system from corrosion, prevents water contamination in sensitive applications, and extends the service life of downstream filtration and drying equipment.

Extended Equipment Lifespan

Maintaining proper after-cooler function directly contributes to longer compressor service life. By preventing overheating and reducing thermal cycling stress on air compressor components, this core helps you avoid costly premature failures and unplanned downtime.

Installation Guidelines

Proper installation ensures your after cooler core delivers optimal performance and service life. Follow these essential steps:

1. Preparation and Safety

Isolate the compressor from all power sources and depressurize the system completely. Allow sufficient time for the compressor to cool to ambient temperature before beginning any work. Gather all necessary tools and ensure you have the correct replacement gaskets and seals.

2. System Drainage

Drain all cooling water from the compressor cooling circuit. Remove any residual compressed air from the system to prevent unexpected pressure release during disassembly.

3. Remove the Old Cooler Core

Carefully disconnect all water and air connections from the existing after cooler. Note the orientation and position of all fittings, pipes, and mounting hardware for accurate reassembly. Remove the mounting bolts and extract the old core from the compressor housing.

4. Inspect and Clean

Thoroughly inspect the cooler housing for any debris, scale, or corrosion. Clean all mating surfaces to ensure proper sealing with the new core. Check all O-rings, gaskets, and seals for wear and replace them as needed.

5. Install the New Core

Position the new after cooler core (1621700408) carefully into the housing, ensuring correct orientation. Secure all mounting bolts to the manufacturer’s specified torque settings. Reconnect all water and air lines, taking care not to overtighten or cross-thread any connections.

6. System Reconnection

On ZR compressors, remove any plastic plugs from the compressor water pipes (WI and WO) and connect the pipes to the cooling water circuit. Fit valves in both the compressor water inlet and outlet pipes for future maintenance access.

7. Leak Testing and Commissioning

Slowly reintroduce cooling water to the system and check all connections for leaks. Pressurize the air system gradually and perform a comprehensive leak test. Start the compressor and monitor operating temperatures to confirm the new cooler core functions correctly.

8. Documentation

Record the installation date, part number, and any relevant observations in your maintenance log. Schedule a follow-up inspection after the initial operating period to verify continued proper function.

Maintenance Best Practices

Regular maintenance of the after cooler core is essential to ensure optimal performance and longevity. Over time, dust, debris, and mineral deposits can accumulate on the cooler’s surfaces, progressively reducing its efficiency. We recommend you periodically clean the cooler and inspect it for any signs of wear or damage. If you observe declining performance, elevated discharge temperatures, or visible damage, consider replacing the after cooler core promptly.

    Excellent product, highly recommended.

    We replaced the after cooler core on our ZR400 with this genuine unit from Sekes. Installation went smoothly and our discharge temperatures dropped by 12°C immediately. The compressor runs quieter and we have not experienced any moisture issues since.

    Worth every dollar.

    Zero issues with fitment or cooling efficiency. This core replaced our older 1621600908 part number on our ZR 400 compressor effortlessly. Sekes Mechanical provided transparent communication throughout the international shipping process. Our pressure drop has lowered noticeably, improving our overall plant energy efficiency.
